Bifunctional coupling agent with methacrylate group for free-radical polymerization and hydrolyzable methoxy groups for silanol formation.
Enhances adhesion between organic polymers and inorganic substrates such as glass, metals, and fillers.
Improves mechanical properties—including flexural strength, impact resistance, and moisture resistance—in filled composites and coatings.
Offers excellent hydrolytic stability in formulated systems when properly balanced with pH and moisture control.
Compatible with acrylics, unsaturated polyesters, vinyl esters, and other methacrylate-based resins.
Fiber-reinforced plastics (FRP) and pultrusion composites using glass or mineral fillers.
Adhesion promoters in automotive and industrial coatings for metal and plastic substrates.
Surface treatment of silica, quartz, and alumina fillers in high-performance thermoset compounds.
Reinforcement aid in dental restorative resins and orthodontic materials.
Moisture-cure sealants and adhesives where covalent bonding to inorganic surfaces is required.
